Only if said Democratic Congresscritters refuse to do their duty and put checks and balances on the Executive Branch. It’s not the party affiliation that’s the problem, it’s the “party over country” mindset.
I’d love to be able to point to examples of Republican Congresscritters who aren’t party-first zombies and whores of the Bush White House, but they’re so damn rare these days.
I agree that a focus on winning elections over representation is an unfortunate consequence of representative democracy, but it’s significantly more serious when done at the party level than at the individual level. At the individual level, even if everyone acts like selfish dicks and focuses only on doing what it takes to get themselves reelected, competition will maintain a balance of power, particularly between branches. The Republican Party, on the other hand, has optimized the acquisition and maintainance of power across branches to the point that it is subverting the system of checks and balances designed to give us effective, limited government. This is not an automatic result of the system – it requires a party which is willing and able to capitalize on the benefits of centralized, collective political action.
Like I said, the Republican party can certainly take credit for understanding the system and using it to their full advantage, but that doesn’t absolve them of the fact that doing so has resulted in a government which is less open, less democratic, and less representative.
Best solution to that would be a multiparty system.
