What particular event started reagan's conservative political career?

His resignation from the General Electric Theater was the private event that began reagan's conservative political career.

Explanation:

Reagan was part of the Democratic party and had liberal democratic ideas. In the mid-1950s, he began to approach ideologies of the American political right, many say that this approach arose because of his romantic relationship with Republican actress Nancy Davis.

In 1964, Reagan began working for the General Electric Theater, at which time he gave indications that he was increasingly supporting conservationist ideas.  The content of his speeches became increasingly filled with right-wing ideologies and this resulted in his resignation from the General Electric Theater. This resignation caused Reagan to start his political career with the Republican party and to make serious criticisms of the Democratic party.
