A bitter take on Trump betraying the anti-war voters who backed him — bad news for supporters who thought he would stay out of foreign wars.

• Trump was seen as the one reformer willing to take the abuse — prosecution, an assassination attempt — to change Washington.
• Now he has backed a regime change war in the Middle East, the one thing he swore he would never do.
• To disillusioned supporters, this looks like a betrayal — siding with the same establishment that wanted him jailed and cheered his shooting.
• The deeper worry: that the whole anti-war, anti-establishment image was an act that fooled his most loyal fans.

Outlook: Expect growing anger and doubt among Trump's base if the U.S. deepens its involvement in a new Middle East conflict.
