“It just tells you what deep trouble Donald Trump is in, when you have 50 percent of the country wanting you not just impeached, but removed from office, and the game hasn’t even gotten fast yet,” Brinkley said on-air Friday morning.
“I think once the vote is taken by Congress to impeach him and he’s wearing the ‘I’ on his chest, you’re going to see that movement grow even more," Brinkley predicted.
He added of Trump: “It tells you he doesn’t have a lot of friends, he’s a base politician. He doesn’t know how to turn this around.”

Brinkley noted the successful campaigns of politicians from opposing parties that came after previous presidents also faced political fallout.

He took the high road. He ran on saying, ‘I will never tell a lie to you,’” he said. “He didn’t have to say [the others] lied. Just that ’I’m clean’ and good governance.”
Polling on impeachment has fluctuated in the nine weeks since Democrats launched their probe.
A Quinnipiac University Poll released Tuesday found a slight shift in the president's direction on impeachment. That survey found 45 percent in favor of Trump’s impeachment and removal, with 48 percent against. That was a reversal from the poll's findings last month.
However, a CNN poll conducted after the first week of public hearings in the inquiry found that half of Americans, 50 percent, said Trump should be impeached and removed from office, while 43 percent say he should not – the same margin from a poll conducted in October.
