McCain and Graham are media favorite BECAUSE they’re willing to trash Trump and Republicans for ‘quick quotes’. They’re not ‘mavericks’ they’re both quislings.
There are NO democrat ‘mavericks’ ... the press would NEVER push forward and quote a democrat who sole value is trashing fellow democrats.
More proof the MSM is corrupt and working for the abolition of the two party system. They ARE one with the democrat party.
These two RINOs are allowed to get away with this solely due to the weak leadership of Mitch McConnell.
Like you noted, Rat Senators wouldn’t dare try to pull what McPain and Linda are doing. Their leadership is far stronger and would deliver swift punishment to those who are disloyal - including stripping them of committee chairsmanships and seniority!
