Trump eggs on struggling Sanders' war against Democrats

The presumptive Republican presidential nominee is seizing on Sanders' refrain that the Democratic Party is stacked against him, shutting out his supporters and rigging the rules to favor Hillary Clinton.

Schultz aside, Clinton has won over broad majorities of minority and female voters, giving her the lead not only in delegates but in the popular vote.

[...] that reality hasn't swayed Sanders, whose heavy emphasis on party functionaries and arcane political rules is a notable change for a candidate who's long focused on curbing income inequality, regulating Wall Street and eradicating the influence of corporate money in politics.

When Trump saw Ted Cruz begin to outmaneuver him in the hunt for delegates, Trump started railing against a "rigged" and "crooked" electoral system that he said favored the will of party bosses over millions of Republican voters.

While the Republican system's rigging was more "sophisticated," he said, the Democrats' system was just as bad, because of its use of hundreds of superdelegates — the party insiders who can declare their support for any candidate regardless of who wins primary contests.

In Nevada, chair throwing, shouted profanities and even death threats to party leaders marked a meeting of the state party on Saturday.

Clinton, who is on a firm path to clinching the nomination within weeks, faces the prospect of winning back Sanders supporters, many of whom are feeling increasingly alienated.
