They didn't expend nearly as much energy on the last lying whackjob (Obama) as they are trying to unseat Trump. The reason is that the establishment Pubs don't really care who is president as long as he doesn't require them to help him fix the problems facing the country. They are content to sit on their asses, lie to their constituencies at election time, to win reelection, and feather their own nests. Trump has forced them to shit in their nests and they don't like it.Patriotic billionaires would rather pay more on taxes than have a lying wackjob as president.
Democrats are more driven to achieve their agenda than are the Republicans. That would be a good thing if their agenda was not so harmful to the American people. The Republican agenda, ostensibly, is to save the American people from the Democrat agenda. It takes better people than we currently have in Congress to accomplish that agenda. There are too many Republicans in Congress without testicles (and I don't mean there are too many women).
