IMO, Bush "ignored it" while dutifully playing the role of Lame Duck after the 2006 mid-terms. Both he and his dad thought it was beneath them to forcefully advocate for their policies, to let others do their heavy lifting. Obama's (and Trump's) rise to power was a consequence of that.
Both Bush's, father and son, were "Presidential" and were replaced by democrats for President, Senate and House.
Later McCain and then Romney were "presidential," too. A lot of good, being "presidential" did.
Obama with his genteel speaking manner, marches us towards Marxism.
But Trump is tough and he won. Gen. George Patton was tough, too and he won.
Winning matters.
