Abdul El-Sayed's Michigan Senate campaign is unsettling party insiders and their media allies, who are painting him as too radical to win.

• El-Sayed is polling around 59%, yet establishment voices insist he can't hold the Michigan Senate seat.
• The pushback is framed as fear that a progressive, non-establishment candidate is catching on with regular voters.
• Critics argue party insiders would rather lose the seat than back a candidate their donors dislike.
• The "he's too radical" line is cast as a smear meant to protect money and power inside the party.

Outlook: Expect the establishment attacks on El-Sayed to intensify as his poll numbers hold up heading into the race.
