According to Keech and Matthews, what characteristic increases a candidate's electability?

Experience in political office is considered a significant characteristic that increases a candidate's electability. This is largely because having prior political experience demonstrates a candidate's ability to navigate the complexities of governance, understand legislative processes, and build necessary relationships within political institutions. Voters often perceive candidates with a track record in political roles as more qualified and capable of effectively representing their interests. Such experience can also lend credibility and reassure constituents about the candidate's understanding of relevant issues and their ability to make informed decisions once in office. This perception can significantly influence voter confidence and ultimately sway election outcomes in favor of experienced candidates.
