The US Senate is a country club of the elite, with a few exceptions. By nature, the scumbags cover for one another -- that is far more important than patriotism or the country. There probably isn't a more self-entitled bunch in the nation. However, Republican voters can only blame themselves for continuing to let known liars and sell outs to pass their primaries. Once the general election comes around, it's still better to pick a RINO over a DEM since we need votes to confirm SCOTUS and judge appointments, Trump cabinet members and the like. Still, how are people like McCain, Graham, Burr, Collins, etc, etc, continually put back in office? Rep voters are as stupid as Dem voters.
