This is how you deal with them: you vote for them because they are NOT Democrats. And you pray for the best. You pray that once they are in office and WE HAVE CONTROL OF THE SENATE, they'll fall into line.
That's the best we can do -- unless you're prepared to let the Democrats destroy this country, which is EXACTLY what they have in mind.
"they'll fall in line" is a bit vague. Would you mind expanding on how that will be done? Or, perhaps, a better way to convert RINOS into Republicans?
