I am a 3L at GULC. I'm currently a law clerk for a Senate Committee on the Hill. (I feel comfortable saying this as there are many GULC 3Ls who are law clerks for Senate Committees

I am considering taking a counsel/LA type position in a Senator's personal office on the Hill post graduation. I would essentially be riding some fellowship $$ (thanks, GULC) until after November. Hill hiring is basically frozen right now for any mid or senior level position (especially counsel positions), as everyone is sitting tight to see what happens in the election. I obviously work for a party, but specifying which isn't entirely essential as it's prob 50/50 right now on who takes/retains the Senate. Obviously my party taking/retaining the Senate will influence my job prospects immensely. The outcome of the presidential race will also have an effect. Regardless, I'd say my prospects are very good considering my resume, experience and the connections I've made.
There is, however, a small % chance of disaster based on a perfect storm of election results in November & very bad luck. If I were to, say, work for 6-9 months post-graduation on the Hill (I've already been clerking there since last year part time), disaster were to strike, (meaning I couldn't acquire a Senate LA level position or higher), and I wanted to transition into private practice, how would I fare?
So, to sum my resume up at that point, I'd have:
-6+ months filling a law clerk/counsel/LA/whatever position for Senator's personal office post-grad
-9 months clerking for a Senate Committee while in school
-2L summer boutique litigation firm
-1L summer government work
The Hill jobs obviously contain no litigation work, but I do work on things directly relevant to the practice of law. It's not like I'm running around doing policy studies on the efficacy of windmills or something. Most of my work concerns constitutional law, SCOTUS precedent, how new legislation affects that, etc. and does require analysis of ongoing litigation, both at the appellate and trial court levels.
But if come January next year I decide the opportunities on the Hill aren't worth it... can I go back and start interviewing with private firms (civil litigation) and expect to get bites? Or will they look at my resume and say "this kid is a policy wonk and will jump at the first Hill job that opens and leave our firm." There is, of course, something to be said for practice experience and then going back to the Hill 3-4 years later. I just don't want to do that right now with my foot solidly in the door.
What if we change the hypo a bit and I find myself a successful position on the Hill but decide 10 years from now I wanna give it all up and go into private practice? Will I be laughed at?
My 2L summer job was at a boutique litigation firm, but nothing will be coming of that (for reasons completely unrelated to me). Firm jobs are hard to get right now. Symplicity is pretty bare and I struck out at OCI (18 interviews 2 callbacks). I'm roughly top 1/3 of the class, maybe a little outside of it. I am extremely good at networking (which is how I got myself to the spot I'm in now with relatively little Hill experience to speak of).
I do love policy and politics and I want to jump in on the Hill. I just wonder if I should "play it safe" and go for the litigation experience first and reevaluate 3-5 years down the road. I also wonder how big of a gamble this is. What if I don't get that job I think I will 9 months from now? Am I relegated to begging for court appointed work?
Oh and student loan debt is a concern, but GULC's generous LRAP will likely ease most if not all of that.
I apologize in advance if this post is scatterbrained or my questions are stupid. This is a stressful time. Thank you for your help.
Edit - Oh and I don't have a journal, but I did do some clinic work.
