"Hot" is a simple, easily understood word. So are most of expressions. But not always, as we shall see.
The words "hot potato", for example, give you no idea to the meaning of the expression, hot potato.
Potato is a very popular vegetable in the United State. Many people like baked potato, cooked in the oven or fire. Imagine trying to carry a hot, baked potato in your hand, it would be very difficult or even painful.
Some publicly disputed issues are highly emotional. So the issues must be treated carefully, or they will be difficult and painful if the elected official has to deal with them. As difficult or even painful as holding a hot potato.
One such hot potato is taxes.
Calling for higher taxes means defeat for a politician. And yet, if taxes are not raised, some very popular government programs will be cut. Then, the politician will be unpopular. So, the issues must be dealt with carefully, as the same way as holding a hot potato.
