That's the whole politics of it-
If trump wins and the senate stays repub, they will increase holding and blame the dems next year. It may be sufficient enough to kill ss.
If the senate flips, or the presidency flips, guess who will be blamed (even if it doesn't flip somehow)
that's how it works, repubs fuck it up, dems fix it until people get happy ish, then repubs back in.
Nixon fucked it followed by clinton
Bush fucked it followed by obama
Trump is the only that has managed to get housing, gold, stocks, national debt, and unemployment up all at the same time-and democrats will be blamed somehow when he's re elected you watch
Anyhow it's an ok idea (give people slightly more money now and take slightly more in jan) but you should be able to opt out
