Bivariate regression models

Consider two rival arguments:
1. Spending money helps candidates win elections, and incumbents win more often in part because
they raise and spend more money. According to this view spending money should increase vote
share regardless of whether the candidate is an incumbent or challenger. In other words, there is a
direct relationship between spending and vote share.
2. The effect of spending on vote share depends on whether the candidate is an incumbent or a
challenger. Incumbents already have name recognition and support, so they do not have much to
gain by spending money, but challengers need to spend money in order to make themselves known
to voters. If this is true, spending money will help challengers more than it helps incumbents, so
there is an interactive relationship between spending and vote share.
