Sneak peek: Pence to warn GOP is on "the road to ruin"

What he's saying; "Will we be the party of conservatism, or will our party follow the siren song of populism?" Pence asks in prepared remarks shared with Axios.

• "A leading candidate last year called for 'the termination of all rules, regulations, and articles, even those found in the Constitution' … while his imitators have a demonstrated willingness to brandish government power to silence critics and impose their will on opponents."
• Pence argues that the Republican Party can choose populism or conservatism, but not both, because conservatives embrace checks and balances while populists scorn them.
• He also warns that the GOP risks standing for little more than "personal grievances and performative outrage."

State of play: Pence sits at around 5% in the GOP primary polls, with Trump over 50%.

• Meanwhile, Pence could be a key witness in the legal cases surrounding Trump's alleged efforts to overturn the 2020 election results.
