It’s much easier to raise money when you’re not in power. You can detail all the things that you WOULD do if you were in power “We will repeal Obamacare on day 1 if we regain power!”. Knowing that they won’t, even if they have to designate someone to vote against their bills.
Why? If Trump solves all the “big name” problems it leaves the GOP nothing to run on. They need big name items to make sure that they can fundraise and get re-elected.
Do I like it? OF COURSE NOT. But this is how things seem to be to me.
