The idea that Trump would have an approval in the 30's and it wouldn't affect GOP in other races was pretty foolish IMO. The mental midgets in this forum angrily posted when I pointed that out.
FWIW, I think Trump's numbers will improve after the Syria strike (assuming it doesn't turn out that the raid was based on wrong evidence). But he's a bonehead so he'll blow it again.
President Trump's actions will definitely have an impact on future GOP races. IMHO it wasn't necessarily Trump's popularity that won him the presidency. There were two groups of people who voted for him; those who wanted to stop Hillary and hopefully place a conservative on the bench and those who worshiped him. Interestingly, he has delivered to those who voted for him out of necessity and so far has failed to deliver to his 'fan' base. His attempts at building the wall, repealing Bammycare and restricting immigration from areas of known terrorism have so far been stymied.
He took quick and decisive action in Syria, which so far has been a feather in his cap. War is never popular, but weakening our military and our resolve around the world has proven to be even more unpopular and perhaps President Trump's actions have come too late. I expect retaliation. I'm just hoping we have the time to increase our military.
