Assuming, of course, they had some to begin with.

Both believe they have plenty of time to try to regain connection to their "base"

I know that's disgusting but if you want to understand crazy you have to throw away all logic and reason. They hate 'liberal," and they are racists. They crave power to impose their religion and minority, extremist views on the rest of us.

What do they have to lose by lying for the miserable #fakepresident? It's the same tactic used by Putin: disrupt and sow discord and discontent. Radicals do this.

It's a win-win to them.

I think their handlers,lobbyists and money men tell them to do it... They and their family will be taken care of so why worry..

It is very unlikely that what they say today in January 2018 will be brought up in November of 2020. Perhaps, maybe their over all support of Trump could be an issue in 2020, but that is a long way off. Plenty of time to lie about whatever they want to lie about. Tom Cotton is from Arkansas, David Perdue is from Georgia Looks pretty safe for both of them....even 32 months into the future.
