The No. 3 Senate Democrat says a two-party primary would undercut the tea party movement.
New York Sen. Chuck Schumer says a number of states let voters of all parties participate in a primary, with the top two vote-getters deciding the election in a runoff.
Schumer says this can result in more moderate Republicans and independents prevailing.
Schumer is speaking to the Center for American Progress. He’s rallying Democrats to defend the government, which is widely criticized by the tea party.
In excerpts from his speech, Schumer highlights what he describes as the divide between tea party elites, specifically mentioning the Koch (kohk) brothers and grass-roots tea party members.
