I suspect that a lot of conservatives from other states will be willing to help underwrite (at legal levels) the challenger's races (primary and general).
Linseed is facing three good, solid conservative primary opponents.
Which is not a bad idea, since if Linseed doesn't gain a majority, there will be a run-off vs the highest ranking conservative.
Which is exactly the scenario that Ted Cruz followed in defeating prohibitive favorite Lt. Gov. David Dewhurst in Texas.
