Tucker Carlson says he's leaving the Republican Party, and several other big media names are walking away from both parties too — a sign of deepening voter anger at the two-party system.

• Tucker Carlson, a lifelong Republican, says he's done with the GOP because it puts a foreign country's interests above Americans'.
• Marjorie Taylor Greene echoed him, saying she won't back an "America last" party but isn't becoming a Democrat either.
• On the other side, Joy Reid signaled she may leave the Democrats over their unconditional support for Israel.
• The common thread: anger that both parties answer to donors — especially pro-Israel money like AIPAC — instead of voters.
• Independents are now the largest voting block, fueled by people who feel betrayed by the party they used to back.

Outlook: Expect more high-profile defections and louder fights over Israel and donor influence as both parties lose grip on disillusioned voters.
