You think getting along is always capitulating, but a leader gets along by drawing others to their side. That’s what Reagan did, but I guess you’d say he shouldn’t have been president then.
There’s no point to having taxpayers fund a politician that either capitulates or alienates his party because they don’t accomplish what they are voted in for and paid for.
"Go along to get along" defines capitulation.
From your comment, I gather that you favor Mitch McConnell and the Republican Senate rank & file to the Cruz/Lee/Sessions faction.
I know you don't. But that's what you're inferring.
