I disagree. Incumbents usually don't have primary opponents. I'd submit that being subjected to a regular diet of primary opponents would probably improve the general level of congressional responsibility, if only by making the Representatives and Senators more accountable to the voters.
I agree about the regular diet. But the open primaries are still an abomination whose eventual mischief could have
been predicted when they first began to fester. I give you the current state of affairs roiling the Republican Party
approaching their convention as evidence. I say again,
nobody knows how many actual, genuinely committed
Republicans voted for Donaldus Minimus in the primaried, pending any release of any actual, tangible numbers.
It could very
well be that Donaldus Minimus as the presidential candidate is, in a manner of speaking, a
nominated Republican in name only.
On the other hand, it also makes the seat more vulnerable to being taken by the other party. But I think increased accountability is probably worth the risk.
Little enough remarked, at times, is the prospect for reverse coattails if Donaldus Minimus shakes out of the
convention as the nominee. The distaste for him could very well have a disastrous effect on the down-ticket
races.
