Full of hot air
When you say someone is full of hot air you mean they talk a lot but are not sincere.
My boss keeps promising to give me a pay rise but the extra money never comes. He is full of hot air!
Some politicians are full of hot air. They never consider what's best for the nation. Their main concern is what's best for themselves.
