On both sides, yes. I'd say the Democrats are more dishonest. GOP claims to be the pro-business party, so no surprise when they act that way. Democrats take the corporate money, pay lip service to the left, and act pro-business as well. Look at Obamacare - we didn't get single payer, we got government subsidies for insurance companies.
Obamacare was a compromise precisely because the Democrats had to make it palatable to Republicans. If it was upto Democrats, they would have passed Single Payer.
